This game is in fact really hard... looks like most of us have difficulty with it... personally, it took me several hours to be able to "clear" this game and finish winning. And I was only trying to use my instinct to won, else, I don't think I would have been done it... It's just a true challenge to hardly see these opponents coming...
I agree with you there, I'd like it if there was an option each time you chose a minigame, you had the choice to turn perspective mode on or something.
Eevee: The character has no effect. It's how good you are that matters. People say Mob Sleds is tough. It is not as hard as you think. Just survive for 30 seconds and there. I beat it on Perspective Mode on like my 3rd try.
